框架技术-hiberntae查询mysql库字段是char类型的有关问题

	StringBuffer sb = new StringBuffer();
	sb.append("select opcode, opname, parent_opcode, menu_level, top_parent_opcode, "
	+ "top_top_parent, system_type, haschild, url "
	+ "from ad_op_code_right ald where 1=1");
	sb.append(conditions);
	if (pageVo != null) {
	PageUtil.generateConditions(pageVo, sb);
	}
	SQLQuery query = session.createSQLQuery(sb.toString());
	List aldList = new ArrayList();
	List opCodeList = new ArrayList();
	// 手动映射，解决hibernate 对char类型字段映射问题
	query.addScalar("opcode",Hibernate.INTEGER);
	query.addScalar("opname",Hibernate.STRING);
	query.addScalar("parent_opcode",Hibernate.INTEGER);
	query.addScalar("menu_level",Hibernate.BYTE);
	query.addScalar("top_parent_opcode",Hibernate.INTEGER);
	query.addScalar("top_top_parent",Hibernate.INTEGER);
	query.addScalar("system_type",Hibernate.BYTE);
	query.addScalar("haschild",Hibernate.BYTE);
	query.addScalar("url",Hibernate.STRING);
	aldList = query.list();
